I am getting closer to understanding spur gear selection. I need some help from anyone with experience in these setups. Looking for spur/pinion combos for an indoor clay track with a T4.
option 1: Tekin RS with express duo2 motor (17.5)
option 2: Castle Creations sidewinder with 4600kv
option 3: Castle Creations sidewinder with 5700kv
THANKS IN ADVANCE
